Subbu and other newbies: I wrote a column for PCD&M on this topic of "What causes reflections", where I derive the reflection coefficient. It is available for free download from my site, www.BeTheSignal.com <http://www.bethesignal.com/> , under the feature articles and columns heading. Look for Aug 2003, "what causes reflections" If you are a newbie and wondering about these sorts of questions, you might want to browse the other columns I posted. Also get a copy of my book, Signal Integrity Simplified. These and other similar topics are covered in my columns, articles, online lectures and the book. --eric ************************************** Dr. Eric Bogatin, President Bogatin Enterprises, LLC Setting the Standard for Signal Integrity Training 26235 w 110th terr Olathe, KS 66061 v: 913-393-1305 f: 913-393-0929 c:913-424-4333 e:eric@xxxxxxxxxxxxxxx www.BeTheSignal.com **************************************** -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of sub mani Sent: Sunday, August 19, 2007 1:48 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] reflection coeficient Hello all, I was reading about signal reflections.
